Title: Improvements relating to electric switches for controlling road vehicle direction indicators
IPC: B60Q1/14
Filed: 1935-06-28
Abstract: 458,796. Road - traffic signals on vehicles. LUCAS, Ltd., J., and LUCAS, O., Great King Street, Birmingham. June 28, 1935, No. 18519. [Class 118 (ii)] A switch is reset by a pawl engaging a member moved by the steering wheel, the pawl being normally housed in a channel from which it is moved by the locking device of the switch. When the switch arm k is moved into one of its operating positions the spring pressed ball g enters one of the channels o (as shown in the Figure), and forces the relative pawl r into the path of the projection t which is moved with the steering wheel. As the turn is being made the projection t slips past the pawl r but when the steering wheel is being returned, the projection t forces the pawl r back into the channel o so that the locking ball g is forced out of the channel o, and the switch arm k is reset by springs l. In its normal position the ball g engages the central recess p.

Title: Dosing pump for electrolytic baths
Inventor: BRIERLEY CLEMENT LEONARD
IPC: B01L99/00
Filed: 1963-05-10
Abstract: <PICT:1044662/C6-C7/1> Apparatus for automatically replenishing an electrolytic bath includes a dosing mechanism which is operated by electric pulses derived from a circuit responsive to the current in the bath and which delivers to the bath with each pulse a constant quantity of replenishing material.  As shown, an electrolytic bath 5, 6, 7 is supplied from an A.C. source 1 over a rectifier 2 and bus-bars 3, 4.  A motor 10, whose speed varies linearly with the voltage applied to it, is connected across a resistance 8 in the bus-bar 3, and drives an obturator, e.g. a punched disc, toothed wheel, slotted disc, &c. (Fig. 2, not shown), positioned between a light source 15 and a photo-transistor 16, which thus generates pulses at a rate directly proportional to the strength of the current flowing in the electrolytic circuit.  These pulses are applied over a transistorized amplifier 17 to a relay 18 which operates a switch 19 in an independent electric circuit which includes a bellows type solenoid pump 20 for dosing a constant volume of replenishment material to the bath for each pulse, the amount of material added for each stroke being predetermined by adjusting the throw of solenoid 21 in the pump 20.  The electrolyte 7 the constituents of which are consumed at a rate linearly proportional to the strength of the electrolytic current, is thus maintained at an approximately constant composition, since these constituents are replaced at the same rate as they are consumed.  A metered delivery pump or a tipping hopper may replace the bellows pump 20. One relay unti may operate several pumps for dosing a variety of additives to one bath.

In an air - heating arrangement for a building, pre-cast refractory blocks 12 each having a central flue passage 13 and an air passage or passages 14 alongside but spaced from the flue passage, are assembled above a heat source 10 to provide a central flue surrounded by air-heating passages, the air flow from which is regulated by dampers. Circulated air may be forced through the air passages by a fan 29 or may flow through the passages by convection. In the arrangement shown, all the bedrooms B and living rooms L are arranged around the chimney unit. The arrangement is such that when the fan is on and dampers 31 in the rooms L are open, air is continuously recirculated by the fan through the air-heating passages 14 and rooms L. Grilles or dampers 30 in the bedrooms B are adapted to be closed by this downward flow of air through the airheating passages 14. When the fan is switchedoff the now partially warmed recirculated air may flow by convection upwardly through the passage 14 and into the bedrooms through grilles 30. A damper may be arranged in the flue passage.

Abstract: 1472056 Data processing systems BRITISH FOOD MFG INDUSTRIES RESEARCH ASSOCIATION 18 April 1974 [24 April 1973] 19300/73 Heading G4A A storage location is addressed by an address consisting of a pair of keywords uniquely identifying the location. The address has the sequential format "keyword, space word, key word, end word". A logic circuit rejects any address not having this format. The space word and end word are the same for each address. In the embodiment described the address is keyed in to a store and displayed on a c.r.t. A pointer on the display points to the first word, which is automatically passed to comparators which respectively detect character, space, and end words. An additional comparator may be used to detect a termination word which terminates a sequence of addresses which relate to the same information item. If none of these words is detected or if the keyword is one of a number of forbidden keywords the circuit gives a reject signal. If the first word is a permitted keyword a bi-stable is set and the pointer advanced to the second word. If this is found to be the space word and if the preceding word was a keyword another bi-stable is set and the first reset, otherwise a reject signal is given. The pointer now advances to the third word and so on. If the format is correct the relevant location is addressed. The address may be stored together with the information item or alternatively may be stored with a serial number in an address store, the information item being stored with the same serial number in an information store. The circuit may be modified to recognize addresses having only a single keyword followed by an end word.
